problems with reving past 5000rpm

[starletjosh]

ive just fitted new
hybrid ct9
hdi fmic
blitz access ecu
hks actuator
air filter re locator
and a few other bits and bobs


when im driving i get between 5000-5500 rpm and it splutters and pops out the back.
im not sure but i think its slightly better if i lift off full throttle.

if you have any ideas i will be gratefull.

cheers josh

ure sparkplugs ok.. you checked all pipes and is the car breathing ok

Check plugs, leads etc. sounds like it could be ignition related... best place to start i would say..

its got denso iridium plugs done about 2000 miles and i havnt checked the leads

might try to find a nice set on here thanks lads
